Patent number: 8281356Abstract: A source device 10 transmits streaming data. In a packet receiver 22 of a sync device 20, statistical data acquirer 23 calculates statistical data such as one-way delay time, packet loss ratio, reception rate and the like from the received streaming data and transmits it to the source device.

Patent number: 8239913Abstract: A system and apparatus for generating an output signal includes a receiving system 160 generating a plurality of signals having a first format and communicating the plurality of signals simultaneously through a primary path and a secondary path. A digital video effects module 240 inserting a digital video effect into at least a first signal of the plurality of signals in a primary path. An encoder 182 encoding the plurality of signals into a plurality of transport streams and a multiplexer. A local area network 130 routes the plurality of transport streams to the multiplexer to form a combined signal. A modulator 210 modulates the combined signal to form a modulated signal and a system 202 forms the output signal from the modulated signal.Type: GrantFiled: March 26, 2007Date of Patent: August 7, 2012Assignee: The DIRECTV Group, Inc.Inventors: Michael R. Munsell, Carl Ostrom, Mitchell B. Wasden

Patent number: 8228362Abstract: The invention discloses an image capturing device and an image delivery method which is suitably applied to a video conference. The video conference is held between a local terminal and a remote terminal through a network. The device comprises a processor, a video encoder, an encryption engine and a data transmitting interface. The processor is used to process an original video signal for generating a first video signal and a second video signal. The video encoder is for receiving and compressing the first video signal. The encryption engine is for encrypting the compressed first video signal. The data transfer interface is for transmitting the compressed and encrypted first video signal and the second video signal to the local terminal. Wherein, the first video signal is transmitted to the remote terminal by the local terminal through the network and recovered by the remote terminal, and the second video signal is presented at the local terminal.Type: GrantFiled: June 12, 2009Date of Patent: July 24, 2012Assignee: Quanta Computer, Inc.Inventors: Wei-Min Chao, Chun-Chiao Wang

Patent number: 8223967Abstract: A semiconductor integrated circuit for the processing of conditional access television signals that includes an input interface for receiving encrypted television signals and an output interface for output of decrypted television signals. The semiconductor integrated circuit is provided with some functionality restricted in some way by preventing one or more hardware circuit elements from operating, such as an MPEG decoder, display engine, IO ports or main CPU. To enable the functionality, a subscriber must pay for a service and then receives an encrypted message broadcast to the semiconductor integrated circuit that is decrypted and instructs functionality to be turned on or off.Type: GrantFiled: October 16, 2003Date of Patent: July 17, 2012Assignee: STMicroelectronics LimitedInventors: Peter Bennett, Paul Elliott, Andrew Dellow
